You are a half-human, half-fox, the legendary Jinko, whose ancestors once saved the human Empire from an invasion of Yokai demons. Your name is Leon, and all you remember are the walls of the cage you were imprisoned in by humans.
But now, the collar is destroyed.
The Heart Abyss combat system is sharp and bloodthirsty, just like its main character. He needs to be in the thick of battle at all times to rip health from enemies and replenish energy for magical abilities. The KEY is not to stand still!
Thanks to his heritage, Leon possesses an impressive reserve of Qi energy. Rain lightning down on your enemies' heads, shoot them with deadly energy, and... who said foxes can't create a small singularity?
Visit various corners of the Empire – from the majestic Capital to the Temple of Death, lost amidst snowy mountains. Meet interesting people and mythical creatures from Japanese folklore. Tear them to shreds (if they are warriors of the Empire).
With Leon, immerse yourself in the aesthetics of Japanese folklore, ancient temples, and Yokai demons. Here, bloody katana battles coexist with delicious ramen, torii gates, and blooming sakura.
A hundred years have passed since the invasion of the Yokai demons. The Human Empire oppresses all other magical beings, and the legendary Jinko have not been seen for many years.
Leon must uncover the reason for his people's disappearance and, perhaps, save the Empire once again. Or, conversely, plunge it into the abyss of chaos.
